Application led December 23, 1924, Serial No. 757,?52, and in BelgiumDecember 29, 1923.v

The present invention relates to automatic inflaters the object of which1s, 1n particular, to allow of iniiatnig tires, or other similar uses byutilizing one o'tthe Vpistons of the 5 explosion engine on the cylinderof which it is mounted, as a compression piston.

Devices ot this kind are usually tixedly mounted on one oi.' thecylinders of the-inotor in place of one of the plugs provided above thevalves, the plug thus replaced being usually the one which correspondsto the exhaust valve.

In case of the motor not having any such plugs it.` is likewise a matterof vordinary knowledge to mount appliances or' this kind on one of thearms of a tubular piecel shaped like a Y, or the like, the other arm ofwhich receives the sparking plug; the whole device thus termed beingscrewed on the motor 1n the place of one of the plugs. v

The invention relates especially to inflaters ot' a known type,comprising an aperture for admission into theV cylinder, a deliveryaperture and an open-air inlet. The object of this last inlet is toallow the induction into the cylinder of a quantity of fresh air throughVthe iniiater, this arrangement permitting the admission into thecylinder of a'suliicient quantity of fresh air to preventthe formationof a carburetted mixture subject to ex'- plosion. Y A Y The fluiddelivered by the niston will consequently be relatively cold and willconsist for the most part of pure air. 1

`llniaters'otl this kind known to this day gene-rally havethedisadvantage of'relatively great complexitv, entailing inparticularhigh expenses of machining. On the other hand these deviceshave several valves and there result, during the operation of theappliance, high inertia forces, due to the great mass of the workingparts. Consequently it is'necessary, with a view to ensuring the safetyof the device likewise to increase the dimensions of the organs.

The object of the present invention is to avoid these drawbacks by meansof a very simple device, in which the mass ofthe working parts isreduced to the minimum.

For this purpose the control of the two above mentioned admissionapertures is effected by a single valve, which is actuated by a.suitable operating agency.

This valve is connected to its operating agency by an elastic link,while a stop limits its displacement in a given direction so that thevalve is able to open under the suction of the engine when it shuts oilVadmission of free air, whileit is heldagainst 'its seat by the abovementioned stop when brought into the position in which it shuts off theg aperture of admission into the cylinder.

Other characteristic features ofthe invention will appear froin'thedescription of the Y inlet. Y l

Fig. 3 is a section of the inflater in a position of operation.l Fig. 4represents a` section'of the iniiater in the course of operation.

The iniiater consists ot' a cylindrical body l screw-threaded in itslower part and re- Vceiving in its upper' part a cap 2.

The body l and the cap 2 are respectively provided with valve seats 3and 4, against which the valve 5 may be brought byv a suitable operatingagency.

According to the embodiment showmthis operating agency consists of athreaded rod 6 screwed into a'suitable prolongation of the cap 2. v

The valve 5 is provided with a nozzle guide 7 which enables it toslide'along the lower part of the rodV 6 and is pulled towards a collar8 integral with the rod 6, by a spring 9 placed inside the said nozzleguide and having its support on the one hand against 'an enlarged base10 of the rod 6 and on the other hand against a iangeV of they saidnozzle Vpiece 7 i It will be seen that from this arrangement thescrewing of the threaded rod 6, effected by acting on a milled button llconnected to it by some suitable means, will cause the downward movementof the rod l6 which, owing to the collar 8, will force back the valve 5until it bears against its seatV 3. as shown on Fig. 1.

In this position the admission from the driving cylinder, not shown,into theiniater is cut olf and the inlater does not operate.

To bring it into its position of action, ity will be sufficient to carryout the reverse operation of unscrewing theY threaded rod 6 and l 70moment when the valve shuts oil.V the free air be driven `upvvaijrls bylio Vsion 'Leif @the spring; ,9L
